Looks pretty decent!
Feel free to disregard any of the following as they are only suggestions:
*I would use a different font that is easier to read perhaps Arial
*Combine "Serviced and supported over 100 personal computers. Performed preventive maintenance, adware detection and removal." into something like this:
Performed preventive maintenance, adware detection and removal, as well as general support services on over 100 personal computers.
*In your description of work experience don't assume the reader knows what .ASP means say
Developed several Active Server Page driven.... instead and maybe use the word interfaced instead of interacted.
*Expand on how successfully you managed your budgets if at all possible.
*Make certain all your font sizes/styles are the same. It may just be the text you posted but it doesn't appear they are.
*Instead of easy interface I think user-friendly interface is more appropriate
*Again don't assume the reader know's what PC's are or at least spell it out just for asthetic purposes
*Looks like you use periods at the end of some sentences and not others when really you should not use them at all with bullets
*Some resume reviewers are anal about the number of bullets under each work experience description being equal
Overall looks good though!
Best Wishes!
